Reuters is reporting that, for the the first time ever, Twitter has brought in $1 billion in revenue in a single quarter.

The company has had a difficult few years as it grappled with the balance between free speech and the spread of misinformation. With an upcoming election, the company has rolled out new policies designed to tackle these problems. The company has also taken steps to fight trolls and online abuse, as well as focus on relevant and useful content.

The end result has been an increase in the “average monetisable daily active users (mDAU), or users who see ads when logged in through twitter.com or Twitter applications,” according to Reuters.

As a result, Twitter’s stock closed at $38.41 a share, up 15%.
